EURORACK MODii Dual VC Modulator
Synchronized Modulation
The top half of the MODii is a DUSG style function generator. Useful additions include an output SHAPE control, and voltage controlled gate DURATION via switch, knob, and cv input. The bottom half comprises a VC decay envelope and a sample and hold circuit. The decay envelope is synchronized to the top half’s function generator via shared use of the trigger and gate inputs. A VC trigger delay allows this synchronization to be broken. The sample and hold circuit is fed via the TIME CV input and stabilizes the decay time’s modulation through-out the duration of the envelope. This S&H modulation voltage has it’s own dedicated output

INSTRUCTION
- Modulator A outputs: Modulator A’s principal output is OUT A. The TRIG input produces an A(S)R (0-8v). The GATE input slew processes incoming voltages. EOC A is high (5v) when there is nothing present at OUT A.
- ATTACK A & DECAY A control knobs: Manual controls for Modulator A’s attack and decay times.
- DURATION control knob & switch: When the switch is set to INT, the DURATION knob controls an internally generated gate’s length. When set to EXT, the duration is set by the input gate’s length.
- SHAPE control knob: Provides a continuously variable output shape to Modulator A as indicated by the panel graphics..
- CYCLE/ENV switch: Sets Modulators A & B in either CYCLE or ENVELOPE mode.
- DURATION, ATTACK, DECAY cv inputs: External cv inputs for associated manual controls.
- DELAY B & TIME B control knobs: Manual controls for Modulator B’s trigger delaylength and envelope decaytime.
- DELAY & TIME cv input: External cv inputs for associated manual controls. TIME CV supplies the S&H voltage.
- Modulator B output: Exponential decay envelope output (0-8v).
- Sample & Hold output: DC voltage output sampled from the TIME CV input, and held for the duration of the envelope.
- TRIG & GATE inputs: TRIG and GATE both trigger Modulators A & B simultaneously. GATE is a VC slew processor input.
- Envelope indicator LEDs: These leds indicate the output status of either modulator. Modulator B’s delay time is shown in green, while the envelope duration shows red.
